CNC mill – Design and functions
On closer examination of the CNC sector and related milling machines, we find the CNC mill is very popular. This fact encouraged us to answer some questions regarding portal milling machines:
- What is a CNC mill?
- What is this machine type used for?
- Which software is suitable for working with a milling machine?
- Which points are important when buying a CNC controlled mill?
Construction of a CNC mill
A CNC mill describes as the name indicates, a particular building type of a milling machine. Here, the X-axis is arranged horizontal, the Y-axis vertical, and the Z-axis perpendicular on the two other axes, which together results in a so-called portal. Some portal milling machines have multiple milling heads on the Z-axis, in addition to the milling head on the Y-bridge, to allow simultaneous processing of all sides in one step.
The workpiece to be machined is either mounted on a movable clamping table which moves within the portal in accordance with the desired material to be removed, or on a stationary clamping table which is travelled by the sled of the milling machine.
Which software is suitable for working with a CNC controlled mill?
A CNC mill operates like all milling machines with a so-called control software. Things which were manually done in the past with drawing paper and pencil, happens today, with much less effort, using a PC. Thanks to modern CAD (Computer-aided design) / CAM (Computer-aided manufacturing) control software, it is possible to send data sets, usually called DIN ISO G-codes, of almost any shape, whether 2D or 3D, to the machine. The machine then works row by row, until the workpiece has been processed as desired. Ready is your customized workpiece. Because also here applies:
The better all components are matched to one another, the more efficient and accurate a CNC mill will work!
It is recommended to contact a milling machine manufacturer or vendor for the purchase of a portal milling machine, offering for example free support even after purchase. This ensures that any initial difficulties, during incorporation into a control software are technically supported by experienced staff, in order to avoid additional, high costs. This makes the start much easier and cheaper!
Which points are essential when buying a CNC mill?
You should ask yourself the following questions before buying a CNC mill:
- What type of material do I want to process and how hard is it regarding the engine power of the milling motor? Hard or soft? Heat sensitive?
- What are the maximum sizes of my workpieces concerning the size of my desired milling machine?
- Which quantities do I want to manufacture in one operation?
- How exactly do the features of my chosen portal milling machine match the needs of my workpiece to be processed?
- Do I feel well-advised?
- Do I get expert support even after purchasing, possibly even free?
The more precisely you can define the requirements of the desired machine before buying, the more accurate a competent seller can offer the right machine, and then the more precise the milling results will be achieved. In a professional, experienced company, you will always have a trained technician and/or seller.
OPERATING COSTS – T-REX N-SERIES
High-performance CNC mill requires minimal maintenance
Due to the robust machine construction, these CNC mills require very little maintenance. Nevertheless, an annual visual and basic inspection of the machine and all components is advantageous to ensure a high production quality concerning the tolerances. Besides, you as the machine owner can efficiently perform all necessary standard tasks yourself.
Our T-Rex machine series, both stepper and servo motor variants, have low maintenance and operating costs, as most of the expenses are reduced to lubricants.
For example, a standard lubricant cost for the central lubrication, with the interval’s optimum setting via the software and economical daily use, can be estimated at around 20€ for approximately two months.
Low power consumption
For the largest T-Rex machine’s power consumption with a vacuum table, tool changer and spindle, we can determine a maximum value of 20 kWh. That corresponds approximately to a cost of 5€ (can vary according to electricity provider). The smaller the machine size and the fewer accessories, the value reduces accordingly downwards.
Spare parts supply
Our T-Rex CNC mill supply of spare parts is permanently guaranteed because we have the necessary standard stock components. Thus, in case of emergency, delays, downtimes and failures can be better compensated.
Daily cleaning of the workplace
Without a doubt, the machine and the work area’s daily cleaning extends the CNC mill’s and accessories’ service life. That includes blowing off, sweeping or vacuuming the work area. This way, you ensure error-free production and a trouble-free workflow and prevent machine failure and unnecessary repair costs.
